Appendix B: Finding the MAC Address and IP Address for

Your Ethernet Adapter

This section describes how to find the MAC address for your computer’s Ethernet adapter so you can use the MAC

filtering feature of the Gateway. You can also find the IP address of your computer’s Ethernet adapter. This IP

address is used for the Gateway’s filtering, forwarding, and/or DMZ features. Follow the steps in this appendix to

find the adapter’s MAC or IP address in Windows 98, Me, 2000, or XP.

Windows 98 or Me Instructions

1.

Click

Start

and

Run

. In the

Open

field, enter

winipcfg

. Then press the

Enter

key or the

OK

button.

2.

When the

IP Configuration

screen appears, select the Ethernet adapter you have connected to the Gateway

via a CAT 5 Ethernet network cable. See Figure B-1.

3.

Write down the Adapter Address as shown on your computer screen (see Figure B-2). This is the MAC address

for your Ethernet adapter and is shown in hexadecimal as a series of numbers and letters.

The MAC address/Adapter Address is what you will use for MAC filtering. The example in Figure D-2 shows

the Ethernet adapters’s MAC address as 00-00-00-00-00-00. Your computer will show something different.

The example in Figure B-2 shows the Ethernet adapter’s IP address as 192.168.1.100. Your computer may

show something different.

key.

3.

Write down the Physical Address as shown on your computer screen (Figure B-3); it is the MAC address for

your Ethernet adapter. This appears as a series of numbers and letters.

The MAC address/Physical Address is what you will use for MAC filtering. The example in Figure B-3 shows

the Ethernet adapters’s MAC address as 00-00-00-00-00-00. Your computer will show something different.

The example in Figure B-3 shows the Ethernet adapter’s IP address as 192.168.1.100. Your computer may

show something different.
